1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

introductionIn January 2020, the government of the Australian Capital Territory (ACT) decriminalised the possession and cultivation of cannabis for personal use. This study explored the driving-related attitudes, beliefs and behaviours of ACT residents who are legally cultivating and consuming cannabis.

methodsA two-part cross-sectional study was conducted. Part-1: Cannabis users residing in the ACT were invited to complete an online survey. Part-2: Survey respondents who reported 'currently growing' cannabis were invited to submit a sample of their home-grown cannabis for phytocannabinoid analysis. Data from Parts 1 and 2 were used to estimate participants' usual Δ

resultsN = 385 cannabis users completed all or part of the online survey and N = 52 submitted cannabis samples for phytocannabinoid analysis. Most participants (N = 224/330; 67.9%) reported waiting ≥7 h following cannabis use before driving. However, 21.5% (N = 71/330) reported waiting ≤3 h. These individuals had the highest cannabis and THC intakes of the sample (where known). Further analyses revealed that individuals who expressed less concern about roadside drug testing and the effects of non-medicinal and medicinal cannabis on driving, and who used cannabis more frequently, in larger amounts, and exclusively for non-medicinal purposes were more likely to report shorter 'wait times'. DISCUSSION AND

conclusionA small proportion of cannabis users in the ACT appear to be driving shortly (i.e., ≤3 h) after consuming considerable quantities of cannabis and THC. This behaviour puts them at risk of driving while impaired and incurring legal sanctions. Interventions alerting these individuals to these possible risks are, therefore, warranted.
